* Color Terminology: Horses are often described by their coat colors, and "yellow" isn't a standard term.
* Golden/Palomino: A horse with a golden coat and a white mane and tail is typically called a palomino.
* Other Possibilities: Depending on the shade of yellow, it could also be described as:
* Dun: A light brown with a yellow cast, often with a dark dorsal stripe and black points (legs, mane, tail).
* Buckskin: Similar to dun, but the points are usually a lighter color (often a reddish-brown).
* Cream: A very light, almost white, yellow.
Let me know if you have a more specific description of the yellow horse, and I can help you figure out the most accurate name for its color.
